2.6.0-test8: broken /fs/proc/array.c compilation

[Duncan Haldane]

Hi 
the changes in 2.6.0-test8 break compilation
of /fs/proc/array.c with
CONFIG_PROC_FS=y
CONFIG_PROC_KCORE=y




CC      fs/proc/array.o
fs/proc/array.c: In function `proc_pid_stat':
fs/proc/array.c:398: Unrecognizable insn:
(insn/i 1332 1672 1666 (parallel[
            (set (reg:SI 0 eax)
                (asm_operands ("") ("=a") 0[
                        (reg:DI 1 edx)
                    ]
                    [
                        (asm_input:DI ("A"))
                    ]  ("include/linux/times.h") 37))
            (set (reg:SI 1 edx)

                    ]
                    [
                        (asm_input:DI ("A"))
                    ]  ("include/linux/times.h") 37))

        ] ) -1 (insn_list 1326 (nil))

No problem in 2.6.0-test7

Compiler bogon, not kernel.

OK, This is the Red Hat 7.3 version of "gcc-2.96-113", which
is "special" (RedHat-patched).  It's reacting to the changes in 2.6.0-test8. 
Does this mean that this compiler has now become unusable for 2.6.0 > test7
with /proc support?

I don't know anything about that compiler. You may have to ask RH to
provide a fix.

In general, the register allocator shouldn't shit its pants.
